Several years ago I was diagnosed by a doctor to have IBS and he prescribed tranquilizers for a cure? Said it had to be my nerves. I objected to his theory. I was retired and quite happy; no stress?
Since I don't like to take medicines, I researched the causes of IBS and found out through various natural medicine articles and books that a common cause is the lack of an amino acid in our system as we age. "L-Glutamine". You can obtain it at health stores (I get mine at Sprouts Food Store). What you need to take is 500 MG before each meal. This will help your body to properly digest food and relieve you of the gas, constipation, etc. that IBS causes. This is a 100 percent vegetarian capsule.

I have not had any problems for the last 7 years, even after trying to reduce my need for the pills. Started with the 3 a day, then went to 2, and now I'm down to only one at my evening meal. No side affects, just freedom from stomach problems.

Many women suffer needlessly with this problem. So I hope this remedy works for them.
Good luck.
